There have not been any talk of a hands-on with Nvidia's new Tegra 4 reference tablet after the original keynote, since Nvidia decided to hold it back from the press and keep it under wraps. However, the company caved in and let some members of the press to have a quick hands-on.

Although there was not much to see here since there have been other Tegra 4 tablets at the show, Engadget.com notes that the 11-inch tablet was impressively light. They even had a chance to try out the Riptide GP 2, designed for the Tegra chip. The prototype was running on Android 4.0.2 and was running circles around it.

The reference tablet also featured micro-USB, HDMI and storage expansion ports/slots as well as some kind of a dock connector. Of course, it was no wonder that the device would perform well, but we guess that we will see a real showdown of mobile chipmakers at MWC 2013 in February.

You can check out the hands-on over at Engadget.com where you can also see Riptide GP 2 on video as well.

If you are after an overclocked GTX 680, you will have to hold your breath for at least a few more weeks. Despite the fact that desktop Kepler GTX 680 launches on the 22nd of March, this will only be the case for reference cards.

Of course, reference cards have the same 1006MHz clock. Additionally, most of them, if not all, will have the same reference coolers with a brand sticker on top of it.

Partners are working on overclocked cards and they should come in a few weeks time. Naturally, Nvidia wants to use the launch and benefit from the sales of reference cards.

There should be enough space for overclocking since the cards can run between 10 and 20 percent over its default 1006MHz clock and remain stable. The question is what will be the safe number to ship the cards at, because when you sell an overclocked card, you have to make sure that it can run for a long time without breaking.

Nvidia’s GTX 680 is a 195W TDP card and overclocking it will make it even hotter, so no surprise there. Overclocked cards should rear their face at some point in April, with a change to get pushed in May being a possibility as well, but they are coming.

Google has asked the Internet Engineering Task Force (IETF) to have a look at the bitstream specification for its VP8 video compression algorithm. Google said that the move was not a move towards standardization but had the aim of creating a definitive reference for the technology.

IETF publishes Request For Comment (RFC) memoranda, used to describe various technologies used on the Internet. The draft does not describe the codec and it admits that there might be differences between the draft and the reference source code published by Google.

This would make it difficult to get the everything nicely standardised, but would mean that the search engine outfit wants a better specification that allows implementers to support VP8 without having to make reference to thousands of lines of source code. However it does show that Google is putting a lot of weight behind V8.
